the number means. How are your example numbers determined?
I'm also not clear on the application.
What species of wood are you talking about?

Subject: Cross-grain Compressive Strain in Timber
I'm doing some casual analysis of metal support plates bolted to the
side of, say, a built-up 2x10 beam. If I try to use, eg, concrete
section analogy, I need to know a strain modulus for the timber (yeah, I
know timber doesn't behave like concrete). What cross grain modulus
might I use?
Eg: conc = .0035, masonry = .003, steel = .002 I could see a virtual SE
= .007? I know that ASTM tests to develop bearing stresses and lengths
invoke the concept of strain = del L/L and I also am aware that the
value must be very variable espec with MC.
Again, if I use strain compatibility analysis, I have to know what value
to use for the strain modulus .
Thanks
